Definitions
- the invention relates to electrically conductive means and methods of their manufacturing.
- electrochemical power sources such as lithium-ion batteries and supercapacitors
- a pair of electrodes These electrodes are composed of an active electrode layer and an adjacent current collector made of metal foil.
- the internal resistance of the electrode which leads to energy losses and thereby reduces the performance of power sources.
- the internal resistance of the electrode in addition to other factors, is affected by the contact resistance between the active electrode layer and the current collector.
- a special conductive layer contacting the active electrode layer is formed on the surface of the current collector.
- a lithium-ion battery cathode made of amorphous silicon, with a current collector in the form of aluminum foil coated with a non-porous titanium serving as a conductive layer [RF Patent No. 135187 , IPC H01M4/12 H01M4/20].
- An electrode with an aluminum current collector is known, on which a several micrometers thick oxide film is formed, through which an active electrode layer of activated carbon is attached to the current collector by introducing solid carbon granules through the film surface into the current collector, thereby reducing contact resistance between the active electrode layer and the current collector [ US Patent No. 6191935 , IPC H01G 9/00].
- the following substances are used as granules: acetylene black, powdered graphite or crystalline carbon.
- Aluminum foil with a forest of vertically aligned carbon nanotubes on its surface is known [ Journal of Power Sources 227 (2013) p.218-228 ]. This foil has low contact resistance of about 0.42-0.15 m ⁇ /g, which makes it exceptionally attractive for use as current collectors, e.g. in high-power supercapacitors.
- the invention solves the problem of creating metal foil with a conductive layer of lower cost and simpler manufacturing technology.
- the set problem is solved by providing metal foil having a surface provided with a conductive layer comprising carbon nanotubes, wherein the conductive layer is applied onto the foil surface so that the carbon nanotubes are arranged randomly and in an amount of 100 ng/cm 2 -10 ⁇ g/cm 2 .
- Carbon nanotubes may be single wall and/or double wall.
- the foil may be made of aluminum, or copper, or nickel, or alloys thereof, for example, as well as of other suitable metals and alloys.
- the conductive layer may be formed on the surface of the metal foil by applying thereto a suspension containing carbon nanotubes and a solvent.
- the suspension may contain a solvent from the following series: water, ethanol, isopropanol, toluene, organic solvent, n-methylpyrrolidone.
- the suspensioncan further contain a dispersanta surfactant, e.g. from the following series: polyvinylpyrrolidone (PVP), polyacrylic acid (PAA), polystyrene sulfonate (PSS), carboxymethyl cellulose (CMC) and a sodium salt of CMC, lignosulfonates, ammonium salts of polymers, sodium dodecilsulfate, and sodium dodecilbensolsulponate.
- PVP polyvinylpyrrolidone
- PAA polyacrylic acid
- PSS polystyrene sulfonate
- CMC carboxymethyl cellulose
- lignosulfonates ammonium salts of polymers
- sodium dodecilsulfate sodium dodecilbensolsulponate.
- the set problem is also solved by providing a method for manufacturing metal foil with a conductive layer comprising carbon nanotubes, the method comprising mixing carbon nanotubes with a solvent to form a suspension, applying the resulting suspension onto the metal foil surface so that the amount of carbon nanotubes thereon is 100 ng/cm 2 -10 ⁇ g/cm 2 , and then drying.
- Single wall and/or double wall carbon nanotubes are preferably used in manufacturing foil with a conductive layer.
- the foil may be made of aluminum, or copper, or nickel, or alloys thereof, for example, as well as of other suitable metals and alloys.
- a substance from the following series can be used as a solvent: water, ethanol, isopropanol, toluene, organic solvent, n-methylpyrrolidone.
- the suspension may also contain a dispersant, i.e. a substance that forms and stabilizes the suspension, which can be selected from the following series : polyvinylpyrrolidone (PVP), polyacrylic acid (PAA), polystyrene sulfonate (PSS), carboxymethyl cellulose (CMC) and a sodium salt of CMC, lignosulfonates, ammonium salts of polymers, sodium dodecilsulfate, and sodium dodecilbensolsulponate.
- a dispersant i.e. a substance that forms and stabilizes the suspension, which can be selected from the following series : polyvinylpyrrolidone (PVP), polyacrylic acid (PAA), polystyrene sulfonate (PSS), carboxymethyl cellulose (CMC) and a sodium salt of CMC, lignosulfonates, ammonium salts of polymers, sodium dodecilsulfate, and sodium dodecilbensolsulpon
- the proposed metal foil with a conductive layer is shown as a current collector of the electrode in Fig. 1 , where: 1 is the metal foil, 2 is the conductive layer comprising carbon nanotubes, 3 is the active electrode layer.
- Metal foil with a conductive layer is manufactured as follows.
- the prepared single wall and/or double wall carbon nanotubes are mixed with a solvent, e.g. water.
- a dispersant is added, e.g. polyvinylpyrrolidone, and the mixture is dispersed ultrasonically using an ultra-sonicator, thereby producing a suspension containing carbon nanotubes.
- This suspension is then applied onto the foil 1 surface based on the condition that the carbon nanotubes are arranged on the surface randomly and in an amount of 100 ng/cm 2 -10 ⁇ g/cm 2 .
- the suspension may be applied by aerosol spraying, air brush, ultrasonic spray or by any other known method suitable for this purpose.
- the metal foil surface After the metal foil surface is dried, a thin layer remains on it comprising carbon nanotubes 2 in an amount sufficient to ensure its good conductivity.
- the conductive layer reduces contact resistance of the current collector and the active electrode substance 3, to which the foil is attached.
- Fig. 1 shows metal foil with a conductive layer as a current collector of the electrode, where: 1 is the metal foil, 2 is the conductive layer comprising carbon nanotubes, 3 is the active electrode layer.
- the proposed metal foil with a conductive layer may be used preferably in electrochemical power sources as current collectors, but its usage is not limited by this application. It can apparently find other applications as well.
- the single wall and double wall carbon nanotubes are mixed with polyvinylpyrrolidone in a ratio of 50/50 wt%. Water is added to this mixture based on the content of nanotubes in the resulting mixture at a level of 0.2 wt%.
- the resulting mixture is dispersed using an ultra-sonicator.
- the resulting suspension is applied onto the surface of aluminum foil with an air brush based on consumption of the said suspension of 50 to 60 mL per 1 m 2 of the foil area.
- the resulting layer on the foil surface is air-dried.
- the content of carbon nanotubes in the applied conductive layer is 10 ⁇ g/cm 2 .
- electrode resistance is 40 ⁇ .
- electrode resistance is 300 ⁇ .
